After having clobbered too many  very important files and directories that
I wanted to make local symlinks to, I wrote the script below to
make it more difficult for me to clobber my files with sgi symbolic
links. Use it in good health. I would be interested in your improvements too!

#! /bin/sh
# Less dangerious and more user frendly front end for ln -s .
# Prevents you from making symbolic linkages the wrong way and clobbering what
# you want to link to.

clear
# . Version.mac #a macro that records who and how often this is used.

echo "Enter existing file you wish create a link to"
if [ "$1" ]
then
echo "or enter a return to use $1"

        if [ -z "$file" ]
        then
        file=$1
        fi

        if [ -x $file ]
        then
        echo "GOOD. $file exists"
        ls -ld $file
        else
        echo "$file does not exist"
        echo " How do you expect me to make a link to a file I can't find."
        echo " bad bad boy"
        exit 1
        fi
